Don't be too hard on your DH OP as there are literally millions of people that don't get it.
I'm a man and am more into equality than my wife. Neither she or my two daughters see what the big fuss is about. I tried to explain the various points behind the campaign and whilst they can see why campaigners are doing it, think it's too small and insignificant to be worried about it.
I even asked my youngest daughter about it and she was totally indifferent.
When all is said and done, the rationale behind the campaign is sound but for the tiny cross section of society that it affects, it appears to be difficult for many to take seriously given that every aspect of the campaign itself can be found in spades everywhere else.
I asked my wife what concerns her and the Sun isn't even on the radar as we don't buy it, read it or know anyone who does. However, in terms of things that affect society and our daughters we have the following that is almost impossible to avoid, unless you live in a hole.
Almost any TV advert
Pop videos
Almost any advert in any magazine or public billboard
Any department store window display at Valentine's Day or Christmas
Victoria's Secret or any other lingerie store
Sports on TV, especially F1, Motorsport podiums, Tour de France, boxing etc.
The Internet
Every day, all of the above give out the wrong message and as a parent its a daily fight to educate or minimise exposure. By contrast the Sun doesn't even make it on the list.
I'm behind the campaign and what it stands for but can also understand why people don't get it. It's a shame there aren't more signatures but maybe the 250,000 out of a female population of 25 million is to be expected.
